of a library call. The functions strerror and perror give you the standard error message for a given error code; the variable program_invocation_short_name gives you convenient access to the name of the program that encountered the validation error messages from taglibraryvalidator for c error. Function: char * strerror (int errnum) Preliminary: | MT-Unsafe race:strerror | AS-Unsafe heap h3 validation error messages from taglibraryvalidator for c in i18n | AC-Unsafe mem | See POSIX Safety Concepts. The strerror function maps the error code (see Checking for Errors) specified by c print error message the errnum argument to a descriptive error message string. The return value is a pointer to this string. The value errnum normally comes from the variable errno. You should not modify the string returned by strerror. Also,

if you make subsequent calls to strerror, the string might be overwritten. (But it’s guaranteed that no library function ever calls strerror behind your back.) The function strerror is declared in string.h. Function: char * strerror_r (int errnum, char *buf, size_t n) Preliminary: | MT-Safe | AS-Unsafe i18n | AC-Unsafe | See POSIX Safety Concepts. The strerror_r function works like strerror but instead of returning the error message in a statically allocated buffer c print error message errno shared by all threads in the process, it returns a private copy for the thread. This might be either some permanent global data or a message string in the user supplied buffer starting at buf with the length of n bytes. At most n characters are written (including the NUL byte) so it is up to the user to select a buffer large enough. This function should always be used in multi-threaded programs since there is no way to guarantee the string returned by strerror really belongs to the last call of the current thread. The function strerror_r is a GNU extension and it is declared in string.h. Function: void perror (const char *message) Preliminary: | MT-Safe race:stderr | AS-Unsafe corrupt i18n heap lock | AC-Unsafe corrupt lock mem fd | See POSIX Safety Concepts. This function prints an error message to the stream stderr; see Standard Streams. The orientation of stderr is not changed. If you call perror with a message that is either a null pointer or an empty string, perror just prints the error message corresponding to errno, adding a trailing newline. If you supply a non-null message argument, then perror prefixes its output with this string. It adds a colon and a space character to separate the message from the error string corresponding

error number is placed in the variable RC when SIGNAL ON SYNTAX is trapped.
You can use the ERRORTEXT built-in function to return the text of an error http://www.gnu.org/s/libc/manual/html_node/Error-Messages.html message.Some errors have associated subcodes. A subcode is a one- to three-digit decimal extension to the error number, for example, 115 in 40.115. When an error subcode is available, additional information that further defines the source of the error is given. The ERRORTEXT built-in function cannot retrieve the secondary message, but it http://www.oorexx.org/docs/rexxref/a34980.htm is available from the condition object created when SIGNAL ON SYNTAX traps an error.Error ListError 3 - Failure during initializationExplanation:The REXX program could not be read from the disk.The associated subcodes are: 001Failure during initialization: File "filename" is unreadable900message901Failure during initialization: Program "program" was not found902Error writing output file "file"903Program "program_name" cannot be run by this version of the REXX interpreter904Failure during initialization: Program "program" needs to be tokenized.
